CABLE-SQ'EE ZEE.

Specification of Letters Patent.

Application. filed January '7,

York, have invented a new and ,improved- Cable-Sjueezcr, ot which thel'ollowing is a lull, clear, and exact description.

ln,thc forming of cables for suspension bridges and the like, in whicheach cable is lormed ol a plurality ol separate strands or wires boundtogether considerable ditlicultv,w

is often encountered in squeezing the strands` together, to formperfectly cylindrical cable, in lninging sull icicnt pressure to drawall strands into lirin engagement with e ch other7 and in holding thestrands in position while the permanent clamps, wrappings or otherinclosing means, are being placed in position.

rllhe obj cct of my invention is to provide a device which .may beeasily and quickly applied to the mass of strands going to .make up thecable, which will torce them together into a perfectly cylindrical mass,and which may be very readily loosened and moved after the permanentsecuring means has been applied adjacent the point last squeezed intoshape.

Reference is to be had to the accompanying drawings forming a part ofthis speciiication, in which similar characters et' reference indicatecorresponding parts in all the tigures, and in whichY Figure 1 is an endview or' a cable squcezer constructed in accordance with my invention;Fig. 2 is a top plan view of the device shown in Fig. 1, the device fordrawing the members together being broken away; F ig. 3 is a sectionalview on the line 3-3 in Fig. 'l and Fig. -1 is a side elevation showinga inoditied forni o1 pressure-ap,lying means, parts being broken awayand in section.

My improved cable squcczer is formed oll two separate semi-circularmembers 1() and 11, hinged together at one end and having means forforcing the opposite ends together. Each member has an inner bandvportion 12 presenting a smooth slnliace for direct contact with thestrands or wires going to make up the cable, and outside of this innerband portion is an outer or reinforcing' portion 13 of any suitableforni in cross section. The

two members are secured together by a pivot pin 14, one of the membershaving two leaves or "aro ections 15 15 tor receiving Patented June 29,1909.

,i-ixpt `pin, and the other member having t center leal or projection 16disposed intermediate the two leaves or projections 15, 15. frs thesehinged leaves or projections overlap and their inner surlaces lie in thearc ol' the same circle with the inner surlaces ol the two members, itis evident that there is no transverse line or groove extending entirelyacross the device at the hinge and into which any wire or strand couldbe lorced during the squeezing operation. 'lhe opposite end ol onemember is provided with two lingers or projections 1T, 1T, extending onopposite sides ot a central 'linger or projection 1S carried by theother member. 'lhese overlapping i'ingers or projections 1T and 18 liediametrically opposite to the hinge pin 14|- and when drawn past cachother to the proper extent, the inner surfaces of the two members andtheir m'erlap'ping projections at both the upper and the lower portions,lorm a perfect cyliiulrical bore or passage.

For drawing the two members together, each is provided with twoupwardly-extending parallel lugs 19, 19 and cach pair of lugs supports atransverse pivot in 20. These lugs extend upwardly from t ieirrespective members to such an extent that a line connecting the pivotpins 20 will lie entirely outside of the cylindrical bore or passage andbeyond the overlapping iingers or projections 17 and 1S. Connectingthese two pivot pins is a suitable means for drawing them toward eachother and causing the two members to come to the position indicated inFig. 1. 'In the specific form illustrated. in Fig. 17 thispressure-applying means includes two sections 21 and 22, each pivoted toits corresponding pivot pin 20, and one of said sections constituting orhaving a cylinder 23, and thc other constitutingl or having a piston 241mounted within said cylinder. The section 21 having the cylinder 23 isro vided with a cylinder head 25 and a glane 26 tor forming a tightjoint about the piston rod portion ol the section 22. Adjacent thecylinder head 25 is an inlet 27, to which a suitable delivery pipe maybe connected, and at the opposite end oi the cylinder is a smallair-escape passage 28, through which air may enter or escape from thecylinder during the operation ol the device. In use, one ol the sectionsis detached from its pivot pin 20, the two members 10 and 11 are openedup on the hinge pin 14 and are the l brought together again about thelarge number of wires or strands going to make up the cable. TheVdetached section is again secured to its pivot pin 20 and liquid isforced into the cylinder 23 under high pressure until the fingers orprojections 17 and 18 have been overlapped, so that the inner surfacesof the two members lie in the are of the same circle. The permanentclamping means is then applied to the cable to retain the strands inposition, the liquid is permitted to escape through the opening 27, andthe cable squeezer is moved along the cable a short distance to aconvenient point. lt is unnecessary to separate either of the sectionsfrom its member after the device has once been placed around thestrands.

F or use with small cables or in center cores oi large'cables, aturnbuckle may be used in place of the hydraulic means illustrated inFig. l. In Fig. 4 I have illustrated such a turnbuckla which includestwo flat sections sure-applying means. Thus, the two meme bers inthemselves constitute levers and permit oi' a greater pressure beingapplied to the strands ol the cable than is exerted at the pivot pins20.

Having thus described claim as new and desire to Patent:

A cable squeezer, comprising two semicircular members having overlappingleaves or projections at one end, a hinge-pin extending through saidleaves or projections, overlapping fingers diametrically opposed to sail hinge pin, outwardly-extending lugs carried by said members yadjacentsaid ngers, and means for moving said members toward each other andabout said hinge pin, said means including two sections, having theirouter ends pivotally connected to the lugs of the members, said sectionsbeing in alinement with each other between the two connections, and saidsections being longitudinally movable relatively to each other.

In testimony whereof l have signed my name to this specification in thepresence of two subscribing lwitnesses.
